- This invention relates to a baseball training and system and method and, more particularly, a baseball training and system training method that comprises a collapsible and portable collector that directs balls to a throwback unit that is capable of providing multiple adjustments to permit a characteristic, such as a ball size capability, ball return trajectory or angle of ball return.
- 2. Description of Related Art
- In the past, various ball throwing devices and nets have been used to assist training a player, especially a pitcher. For example, some of the devices disclose ball throwing devices in which a pair of rotary wheels are independently adjustable in speed to achieve the throwing of a ball with wide variations in velocity and curvature. Also, nets have been used in the past to collect thrown balls. However, there is no known patent or prior art that provides for a system and method that enables automatic collection of the balls and feeding of the balls which returns the balls to the player who throws the balls towards a target on the collector and in which the thrower is adjustable to accommodate balls of different sizes, to adjust the trajectory of balls thrown and which may be utilized in combination with other features, such as a speed sensor which measures a velocity of the ball and a ball sensor which provides an indication to the player when a ball is going to be thrown at him.
- It is, therefore, a primary object of the invention to overcome one or more of the problems associated with the prior art devices by providing a ball pitching system and method that provides multiple adjustments of a characteristic of the ball throwing device, such as a ball trajectory adjustment and a ball size adjustment.
- In one aspect, the invention comprises a baseball training system comprising a target, a collector for collecting balls thrown at the target by a thrower a throwback unit associated with said collector for receiving collected balls back to said thrower, said throwback unit comprising a base, a drive motor mounted on said base, a wheel coupled to said drive motor, and a guide, at least one of said wheel or said guide being adjustable to permit adjustment of a characteristic of said baseball training system.
- In another aspect, the invention comprises a throwback system comprising a base, a drive motor mounted on said base a wheel coupled to and driven by said drive motor and a guide at least one of said wheel or said guide being adjustable to permit adjustment of a characteristic of said throwback system.
- In still another aspect, the invention comprises a method for returning thrown balls to a player, said method comprising the steps of providing a throwback unit, situating said throwback unit in operative relationship with a collector for collecting balls thrown at a target associated with the collector, adjusting said throwback unit to accommodate a desired ball size and adjusting said throwback unit to return a ball along a predetermined ball return trajectory.

Notice inFIG. 24 that the angle θ is on the order of about 5-20 degrees. - The
collector 12 further comprises a ball speed sensor 76 (FIGS. 17-20 ), that measures and displays a speed of theball 16 thrown at thetarget 14 in miles per hour (mph). Thecollector 12 comprises a front panel 78 (FIG. 16 ) that is pivotally mounted tomember 60 and pivotal in the direction of arrow D inFIG. 16 so that thepanel 78 may be moved to a stored position shown inFIGS. 17-20 . Note that when thepanel 78 is in the position illustrated inFIGS. 1 and 16 , it is slightly angled relative to the ground so that any thrownballs 16 that hit thepanel 78 will be deflected into thecollection area 12 a ofcollector 12. Also, notice that thepanel 78 may comprise atransparent window 80 to protect theball speed sensor 76, while permitting thesensor 76 to capture a speed of a thrownball 16. In the embodiment being described, thepanel 80 is generally planar and made of transparent Plexiglas® to enable the speed to be displayed on a display coupled to thesensor 76. - In the embodiment being described, the
collector 12 collapses as will now be described relative toFIGS. 16-22 . First, thepanel 78 is moved from the down position shown inFIG. 16 to the stored position shown inFIG. 17 , and thefloor 50 is then pivoted upward in the direction of arrow C (FIGS. 17 and 18 ) to the upright and stored position shown inFIG. 19 . - As illustrated in
FIG. 20 , theframe members FIG. 20 . Although not shown, themember 36 may be integral withmember member 36 may be provided separate frommembers ends FIG. 26 . A nut 190 and bolt 192 are used to secure theends 36 a to end 32 a and end 36 b to end 34 a. The nut 190 and bolt 192 can be loosened to enablemember 36 to be pivoted in the direction of arrow E (FIG. 19 ) to the closed position shown inFIG. 20 . In an alternate embodiment, themember 36 may be pivotally coupled tomembers - After the
floor 50 is moved to the stored position shown inFIG. 19 , themember 36 of theframe 28 is moved to the collapsed or stored position shown inFIG. 20 . If it is desired to lock thefloor 50 in a stored position, a retainer 90 (FIG. 21 ) is provided and may be received inaperture 92, as illustrated inFIGS. 21 and 22 . Thecollector 12 haswheels 95 and 97 (FIG. 1 ) to permit the user to roll and move thecollector 12. - The
system 10 further comprises thethrowback unit 18 which will now be described. As illustrated inFIG. 1 , thethrowback unit 18 is situated adjacent tocollector 12 and receives collectedballs 16 through theaperture 68 ofcollector 12. Theballs 16 are retrieved in a collection track or grate 92 (FIGS. 2 and 11 ), which has a latch or hook 94 that is received by a mating U-shaped channel member 96 (FIG. 2 ), that is mounted on themember 58 offloor 50, as illustrated inFIG. 2 . Thetrack 92 comprises afirst track 92 a, asecond track 92 b and apivotal coupling 92 c for coupling the first andsecond tracks coupling 92 c permits theunit 18 to pivot in the direction of arrows F and G relative to thetrack 92 a. The throwback unit may be provided with acage 18 surroundingwheel 24 as shown inFIG. 1 . - Referring now to exploded view in
FIG. 11 , thethrowback unit 90 comprises thebase 20, which has a pair ofwheels brackets screws post 108 on which atubular handle 110 is mounted and may telescope. Thetubular handle 110 comprises a grip 111 and a handadjustable lock fastener 112 for securing thetubular member 110 to thepost 108 after a user adjusts thehandle 110 in the direction of double arrow K to a desired height. The grip 111 andwheels throwback unit 90 to be tilted in the direction of arrow G (FIG. 11 ) so that it can be rolled on thewheels - The
throwback unit 90 further comprises a first adjuster 114 (FIGS. 1 and 12 ) for adjusting thethrowback unit 90 to accommodate different sizes ofballs 16. Theadjuster 114 comprises asupport post 116 having atubular member 118 adjustably and slidably mounted thereon. Thetubular member 118 comprises a pair of brackets or mounts 120 and 121 for providing a ball size as described later herein. Themotor 22 is mounted onpost 118 withbolts 122 as shown. - As best illustrated in the sectional view shown in
FIG. 12 , theadjuster 114 comprises a threadedmember 132 that is threadably received in the threaded sleeve 134 that is integral withtubular member 118 such that when the crank or handle 136 ofadjuster 114 is rotated, thetubular member 118 and drivemotor 22 move in the direction of double arrow L as shown. After adjustment, a threaded lock nut 144 (FIG. 11 ) may be used to lock themembers - It should be understood that the
adjuster 114 enables the system and method of the present invention to be adjustable in order to accommodate balls of different sizes, such as girls' baseballs used in playing hardball and softball or boys' baseballs used when playing softball or hardball. - As illustrated in
FIG. 11 , to facilitate measuring a size of theball 16, thethrowback unit 90 further comprises aball gauge 138 comprised of afirst gauge member 140 and asecond gauge member 142. Thegauge members ball 16, as illustrated inFIG. 3 . The rotatable handle or crank 136 (FIG. 12 ) is rotated until themembers ball 16 until a distance, indicated by double arrow I inFIG. 5 , is set to correspond to the diameter of theball 16. After theadjuster 114 is set to the appropriate ball size, thehand nut 144 may be tightened to lock themember 118 to post 116. - The
throwback unit 90 further comprises a visual ball-size gauge 146 comprising apivotal gauge arm 148, as best illustrated inFIG. 3 . Thearm 148 has an L-shapedspring support 150 that receives a spring 152 that biases thearm 148 toward thetubular member 118 as shown. It should be understood that when the crank or handle 136 is rotated such that thetubular member 118 move in the direction of arrow L shown inFIG. 12 , thebracket 121 cooperates with aprojection 154 mounted onarm 148 to cause anindicator 156 to move along a top surface ofbracket 120. Theindicator 156 cooperates with indicia 158 (FIGS. 7 and 10 ) to provide an indication of the size ofball 16 that is situated between the gauge andmembers 140 and 142 (FIGS. 5 and 8 ). For example, note inFIGS. 5-7 , aball 16 is situated between thegauge members crank 136 is rotated until themembers ball 16 and the distance I generally corresponds to the diameter of theball 16, which in turn causes a distance J (FIG. 6 ) between thewheel 24 and theguide 26 to be adjusted to correspond to the size ofball 16.Indicator 156 cooperates withindicia 158 to provide a ball size indicator. - Further to the illustration,
FIGS. 8-10 show aball 16 of a larger diameter than that shown inFIGS. 5-7 . In this illustration, the rotatable crank 136 (FIG. 3 ) is rotated until thegauge members ball 16. As with the illustration discussed earlier herein relative toFIGS. 5-7 , the distance J between thewheel 24 and guide 26 is simultaneously adjusted to the correct ball size. As with the illustration inFIGS. 5-7 , note that the indicator 156 (FIG. 10 ) also simultaneously moves and cooperates with theindicia 158 to provide an indication of theball 16 size. As with the smaller ball shown inFIGS. 5-7 , theindicator 156 andindicia 158 may be used to provide an initial rough adjustment of the distance J (FIGS. 6 and 9 ) to the desiredball 16 size by rotating thecrank 136 and using theindicia 156 to adjust the distance between thewheel 24 andguide 26. Next, finer adjustments may be made by actually placing aball 16 between thegauge members crank 136 to the desired ball size. - The
system 10 further comprises a trajectory adjuster 160 (FIG. 13 ) which will now be described. Thetrajectory adjuster 160 provides adjustment to enable a user to launch or return theball 16 along a pre-determined trajectory. For example,FIG. 2 illustrates thetrajectory adjuster 160 being set such that it launches aball 16 along a first trajectory T1. Thetrajectory adjuster 160 can be adjusted in the manner described herein to cause the ball to be launched on a different desired trajectory, such as the illustrated trajectory T2 shown inFIG. 2 .FIG. 13 illustrates a sectional plan view of the base 20 showing various details of thetrajectory adjuster 160 which will now be described. - The
trajectory adjuster 160 comprises a post 162 (FIGS. 11 and 13 ) comprising a threaded nut 164 (FIG. 11 ) mounted by conventional means, such as a weld, underneath thegauge meter 142. - A rotatable handle or crank 166 rotatably drives the threaded
member 168 which cooperates with thenut 164 to drivelinkage 170 which, in turn, pivotally drives aconnector member 172. This causes a pivot linkage member 174 (FIG. 11 ) to drive aconnector 173 that causes aguide 26actuator 177 to engage surface 26 a ofguide 26, thereby raising and lowering theguide 26, as illustrated inFIG. 15 . Thus, when a user rotates thecrank 166 in a counterclockwise direction, for example, thelinkage 170 is pulled toward thenut 164. This, in turn, causes thepivot member 177 to engage the surface 26 a ofguide 26 and move it away from thebase 20, thereby causing theball 16 to be returned to the player at the higher trajectory, such as trajectory T2 illustrated inFIG. 2 . Likewise, if it is desired to lower the trajectory, for example, to the trajectory T1 illustrated inFIG. 2 , then the user rotates thecrank 166 in a clockwise direction which, in turn, causes theguide 26 to lower. - It has been found that it may be necessary or desired to adjust the
ball height adjuster 114 after thetrajectory adjuster 160 has been set. It should be understood, however, that a user may adjust one or both of theball height adjuster 114 or thetrajectory 160 as necessary to adjust thethrowback unit 18 to the desired ball size and ball return trajectory. - Advantageously, this system and method provide a convenient baseball training system and method that provides a portable and
collapsible collector 12 with a portable ball return orthrowback unit 18. During use, a player may throw theball 16 at thetarget 14. Theball 16 falls into thecollection area 12 a provided by thecollector 12 and theangled floor 50 causes theball 16 to be directed toward theaperture 68 insidewall 71. Theball 16 falls onto the feed guide or trench 92 (FIG. 2 ), whereupon it is directed toward an area 27 (FIGS. 2 and 4 ) between theguide 26 andwheel 24. - The
rotating wheel 24 cooperates with theguide 26 to return or throw theball 16 back toward the player. In this regard, it should be understood that thethrowback unit 18 may be coupled to thecollector 12 with the latch 94 (FIG. 2 ) as described earlier. Thepivotal coupling 92 c permits thetrack member 92 a to pivot in the direction of arrow F (FIG. 11 ) relative tobase 20. This enables the base 20 to be pivoted toward different players in the field of play, as well as toward a player located in front of thecollector 12. - As mentioned earlier herein, the
system 10 further comprises a speed sensor measure 76 (FIG. 17 ) which measures the speed of an incoming thrownball 16 through the transparent window 80 (FIG. 1 ) and displays the measurement through thewindow 80 to the player. Alternatively, a separate display, such as a larger liquid crystal display may be coupled tosensor 76 and situated adjacent to thecollector 12 to provide a read-out display or display of the speed of theball 16 thrown at thetarget 14. - Although not shown, a computer (not shown) may be coupled to
sensor 76 to collect data regarding pitches thrown towardtarget 14. - Moreover, the
system 10 may be provided with a ball load sensor 180 (FIGS. 3, 4 and 11) which senses when aball 16 is situated in thearea 27 between theguide 26 and thewheel 24 and is about to be returned. Thesystem 10 further comprises an audio output speaker (not shown) coupled to thesensor 180 which provides an audible sound when theball 16 is loaded between theguide 26 andwheel 24. In the embodiment being described, themotor 22 may be model number 2130 available from Leeson Electric of Willoughby, Ohio, thespeed sensor 76 is a model number Speed Check available from Speed Check, of Edina, Minn.; andsensor 180 is a model number PA18 available from Carlos Gavazzi of Cleveland, Ohio. Each of themotor 22,sensor 76 andsensor 180 is coupled to a suitable power source with suitable electrical connectors, all of which are not shown for ease of illustration. - Advantageously, this system provides a convenient means and method for providing a
portable throwback unit 18 that can be situated in operative relationship with a portable andcollapsible collector 12. Thethrowback unit 18 can be adjusted to accommodate numerous ball sizes and can also be adjusted to return a ball along a pre-determined ball return trajectory. Thebaseball training system 10 can be used to return thrown balls to a player or multiple players by simply adjusting the location of thethrowback unit 18. Also, it envisioned that theunit 18 can be used as a field training device such that thethrowback unit 18 can be positioned to throwballs 16 along different trajectories and any desired angle ofball 16 return relative to thecollector 12. Because the base 20 can be pivoted relative to thetrack 92, a trainer can use the grip 111 to adjust the position of thethrowback unit 90 to direct it towards the player in the field. After thethrowback unit 18 throws theball 16 towards a first player, for example, thethrowback unit 18 can be adjusted or moved so that it throws theball 16 towards a second player in the field. For example,ground balls 16 may be thrown at a player in the infield or outfield who throws theballs 16 back towardtarget 14 and into thecollection area 12 a ofcollector 12, which again throws the balls to the player on the pre-determined or desired trajectory. Also, the trajectory can be altered as desired herein to throw line drives, shallow pop-ups, or ground balls. - While the system and method described herein constitute preferred embodiments of this invention, it is to be understood that the invention is not limited to this precise system and method, and that changes may be made in either without departing from the scope of the inventions, which is defined in the appended claims.
